NAME
upgrade_db.pl
SYNOPSIS
upgrade_db.pl -input <oldfile> -output <newfile>DESCRIPTION
This will attempt to upgrade DB files from one version of DBM::Deep to another. The version of the input file is detected from the file header. The version of the output file defaults to the version of the distro in this file, but can be set, if desired.
OPTIONS
- -input (required)
-
This is the name of original DB file.
- -output (required)
-
This is the name of target output DB file.
- -version
-
Optionally, you can specify the version of DBM::Deep for the output file. This can either be an upgrade or a downgrade. The minimum version supported is 0.91.
If the version is the same as the input file, this acts like a compressed copy of the database.
- -autobless
-
In pre-1.0000 versions, autoblessing was an optional setting defaulting to false. Autobless in upgrade_db.pl defaults to true.
- -help
-
Prints a brief help message, then exits.
- -man
-
Prints a much longer message, then exits;
CAVEATS
The following are known issues with this converter.
Diskspace requirements
This will require about twice the diskspace of the input file.
Feature support
Not all versions support the same features. In particular, internal references were supported in 0.983, removed in 1.000, and re-added in 1.0003. There is no detection of this by upgrade_db.pl.
